XYZ Racing Racing Spec Coilovers — Subaru IMPREZA GDA/GDB STI A-D/GGA/GGB (PCD:5 X 100) 2WD/4WD 2000-2007

The GDB Impreza STI carries its EJ-series boxer slung ahead of the front axle, and on standard dampers that nose weight shows up as roll and a soft initial dive every time you load the front under braking. The XYZ Racing Racing Spec coilover is built to take that out of the equation – a track-focused kit for the 2000-2007 5×100 STI and its GGA/GGB wagon siblings, set up for circuit work rather than a comfortable commute.

Racing Spec is the hard end of the XYZ range. Where the road-biased kits chase compliance, this one is aimed squarely at serious track and time-attack use, with damping derived from competition rather than pulled off a shelf.

What this coilover kit does for your 2000-2007 Subaru Impreza GDA/GDB STI

Drop a Racing Spec kit under a 5×100 Impreza and the first thing you notice is how much flatter it stays mid-corner. The reduced roll keeps the AWD platform planted, so power can go down earlier out of slow corners where the STI traditionally washes wide. Firmer, competition-led damping controls weight transfer through quick direction changes – the esses and chicanes where a stock car pitches and settles a beat too late. Ride height adjustment lets you drop the centre of gravity and corner-balance the car, and the support under braking gives you a steadier platform to trail into an apex. On a torque-rich turbo flat-four, that composure is what turns a fast straight-line car into a quick one across a whole lap.

About the Racing Spec coilover

Racing Spec sits at the competition end of XYZ Racing’s coilover range, made specifically for track use rather than fast-road duty. The damper settings weren’t guessed at – XYZ developed them through direct participation in series including the World Touring Car Championship, then carried that knowledge into the kit. The result is valving tuned for circuit loads and repeat sessions instead of ride comfort. For cars running aggressive setups – heavily modified builds, A-class racing machinery, or anything approaching factory race spec – XYZ can also produce custom-made shock absorbers built to your specific combination. Supply the detail on your upgraded parts and the circuits you run, and the dampers can be valved to suit that car and those tracks. For most GDB owners the standard Racing Spec kit covers it; the custom route exists for the genuine extremes.
